Thomas Hallock 3c9406afc5 fix(practice): improve mobile layout + floating abacus positioning 
- Add bottomOffset/rightOffset to MyAbacusContext for virtual keyboard avoidance
- NumericKeypad sets offsets when mounted (48px bottom, 100px right)
- Floating abacus repositions above/beside keyboard in portrait/landscape
- PracticeSubNav: fix horizontal overflow with minWidth: 0 on flex children
- SessionProgressIndicator: allow proper flex shrinking
- ActiveSession: reduce padding/gaps, use flex layout to fill available space
- PracticeClient: use fixed positioning with proper insets for all orientations
  - Portrait: bottom 48px for keypad
  - Landscape: right 100px for keypad
  - Desktop: no offsets needed
- Prevent viewport scrolling during practice sessions

Thomas Hallock 6a4dd694a2 feat(blog): add interactive ECharts for BKT validation blog post 
- Add ValidationCharts with tabbed interface for A/B trajectory data
  - "All Skills" tab: shows 6 skills at once, toggle Adaptive/Classic
  - "Single Skill" tab: interactive skill selector for individual comparison
  - "Convergence" tab: bar chart comparing sessions to 80% mastery
  - "Data Table" tab: summary with advantage calculations
- Add SkillDifficultyCharts for skill difficulty model visualization
- Create snapshot-based test infrastructure for trajectory data
  - skill-difficulty.test.ts generates A/B mastery trajectories
  - Snapshots capture session-by-session mastery for 6 deficient skills
- Add generator scripts to convert snapshots to JSON for blog charts
  - generateMasteryTrajectoryData.ts → ab-mastery-trajectories.json
  - generateSkillDifficultyData.ts → skill-difficulty-report.json
- Add skill-specific difficulty multipliers to SimulatedStudent
  - Basic skills: 0.8-0.9x (easier)
  - Five-complements: 1.2-1.3x (moderate)
  - Ten-complements: 1.6-2.0x (harder)
- Document SimulatedStudent model in SIMULATED_STUDENT_MODEL.md

Results show adaptive mode reaches 80% mastery faster for all 6 tested
skills (4-0 at 50% threshold, 6-0 at 80% threshold).
